单选题The human brain contains 10 thousand million cells and each of these may have a thousand connections. Such enormous numbers used to discourage us and cause us to dismiss the possibility of making a machine with humanlike ability, but now that we have grown used to moving forward at such a pace we can be less sure. Quite soon, in only 10 or 20 years perhaps, we will be able to assemble a machine as complex as the human brain, and if we can we will. It may then take us a long time to render it intelligent by loading in the right software (软件) or by altering the architecture but that too will happen. I think it certain that in decades, not centuries, machines of silicon (硅) will arise first to rival and then exceed their human ancestors. Once they exceed us they will be capable of their own design. In a real sense they will be able to reproduce themselves. Silicon will have ended carbon's long control. And we will no longer be able to claim ourselves to be the finest intelligence in the known universe. As the intelligence of robots increases to match that of humans and as their cost declines through economies of scale we may use them to expand our frontiers, first on earth through their ability to withstand environments, harmful to ourselves. Thus, deserts may bloom and the ocean beds be mined. Further ahead, by a combination of the great wealth this new age will bring and the technology it will provide, the construction of a vast, mancreated world in space, home to thousands or millions of people, will be within our power.

单选题{{B}}Part Ⅳ Cloze{{/B}}Directions: In this part, there is a passage with 15 blanks. For each blank there are four choices mrarked A, B, C and D. According to the U. S. National Highway Traffic Safety Administration (NHTSA) , car crashes are the leading cause of death among children between 5 and 14 years of age. Says NHTSA: "{{U}} (61) {{/U}} 50% of children who die in crashes are unrestrained. In addition, 4 out of 5 children are {{U}}(62) {{/U}} restrained. " The NHTSA offers a number of safety {{U}}(63) {{/U}} and cautions for those who are accompanied by children while driving. {{U}}(64) {{/U}} laws vary from country to country and even from state to state, these guidelines may serve as food for {{U}}(65) {{/U}} to many parents and guardians of children. The safest place for all children is in the back seat. Infants should be placed in a rear-facing child safety seat in the baekseat of the car. A child {{U}}(66) {{/U}} a year old and weighing at least 20 pounds may be placed in a forward-facing seat. At 40 pounds, the child can use a "booster seat(儿童案例椅) ", {{U}}(67) {{/U}} is secured by one of the car's lap and shoulder belts.

单选题{{B}}Passage Four{{/B}} The world is full of new horrors and there's no place to hide. Who says so? Disaster psychologists, for a start. They are the people who take in the big picture of our collective reactions to human-created disaster, the ways these reactions are caused, and our coping mechanisms. And research into disaster psychology is growing fast. Among the big issues being addressed by these researchers are understanding the terrorists' weapons, assessing the full impact of terrorism—and, crucially, working out which psychological approaches actually work. It's a deeply controversial area. Take the work of Dennis Embry as an example. He argues that we have overlooked the obvious. the purpose of terrorism is to create terror. This works best "if the very symbols of everyday life become conditioned fear and anxiety stimulant". The top targets will be the most symbolic of a nation's daily life, preferably served up for prime-time television. Crashing planes from United and American Airlines into the Twin Towers and the Pentagon from 8.46 am on met those objectives all too perfectly. After the attacks, people stopped flying. Why? Not because they had made a rational risk assessment but because the mere thought of flying made their palms sweat. From terrorism to rail crashes, counseling and "debriefing” are the standard response to help those caught up in disasters. But there are growing doubts about their effectiveness. What might be going wrong? Debriefing focuses on getting people to talk through the trauma(创伤)and its emotional consequences soon after the incident. Could it be that some people are better by distancing themselves from what happened, rather than retelling it?

单选题{{B}}Passage Two{{/B}} When I was home in Britain on holiday last summer, I spent an evening looking at photos my father had taken when he stayed with us in Beijing in the spring of 1966. Of all these interesting scenes of the past, the one I exclaimed at was a photo of Chang An Jie at Tiananmen. The photo showed one car and two bicycles! This made me reflect on the changes that have transformed Beijing since I came to the city 37 years ago. In those days, the bicycle was king. What sheer joy it was to cycle along with the hundreds (not thousands) of fellow pedallers (骑车人), never in fear of life and limb as one is now. I bought my first bike in 1963. It cost me 150 yuan-in those days three or four months' salary for the average city dweller. Such changes! Good or bad? Today, cycling is hazardous but bikes are easily affordable. Gone are the old wooden houses I remember in south Beijing and fast disappearing are the small, overcrowded courtyard houses lacking running water, central heating and bathroom. Very many Beijingers now live in more convenient, better-equipped flats in high-rises. But these very high-rises are swallowing up the unique character of the old city of narrow hutongs, age-old siheyuan and close-knit communities. I loved years ago to cycle to Beihai to visit my friends (I then taught at China Foreign Affairs University). In spring I rode through the blue-green wheat fields, in summer through fields of tall maize (玉米). Further west; beyond Beijing Foreign Studies University there were the vegetable fields of the Evergreen Commune (四季青公社) and the rice paddies glistening in the summer sun. But now, as Beijing stretches out further and further, west, east, north, south, there's decent housing for families, busy offices for employment and large department stores and supermarkets where, if you have the money, there's little you cannot buy.

单选题Even plants can run a fever, especially when they're under attack by insects or disease. But unlike humans, plants can have their temperature taken from 3,000 feet away—straight up. A decade ago, adapting the infrared scanning technology developed for military purposes and other satellites, physicist Stephen Paley came up with a quick way to take the temperature of crops to determine which ones are under stress. The goal was to let farmers precisely target pesticide (杀虫剂]) spraying rather than rain poison on a whole field, which invariably includes plants that don't have pest (害虫) problems. Even better, Paley's Remote Scanning Services Company could detect crop problems before they became visible to the eye. Mounted on a plane flown at 3,000 feet at night, an infrared scanner measured the heat emitted by crops. The data were transformed into a color-coded map showing where plants were running "fevers". Farmers could then spotspray, using 40 to 70 percent less pesticide than they otherwise would. The bad news is that Paley's company closed down in 1984, after only three years. Farmers resisted the new technology and long-term backers were hard to find. But with the renewed concern about pesticides on produce, and refinements in infrared scanning, Paley hopes to get back into operation. Agriculture experts have no doubt the technology works. "This technique can be used on 75 percent of agricultural land in the United States," says George Other of Texas A&M. Ray Jackson, who recently retired from the Department of Agriculture, thinks remote infrared crop scanning could be adopted by the end of the decade. But only if Paley finds the financial backing which he failed to obtain 10 years ago.

单选题I'd been living with my wife for eight years and one night. Morn says, "I guess you guys are never going to get married. I mean, you've been through jail together, you're living together, but…, oh, forget it." "Oh, well," I said," put it like that and I'll marry your daughter tomorrow." Actually, I don't know what we were waiting for, except that for a guy it's never the right time to get married. I' m also suspicious of any two people who don't struggle with that decision. Part of my problem was that I was still lusting in my heart after other ladies. But somehow I knew that I wasn't going to find another woman remotely as great as my soon-to-be wife. It's a good thing my mother-in-law finally spoke up. I finally gathered my courage one day when we were having a picnic, and popped the question. I also gave my wife a big tourist pamphlet about Switzerland. I wasn't taking any chances. She said no. It killed me. I felt sick to my stomach. I lost my appetite. Our dog just stared at me, thinking, "If you're not going to eat your lunch, I will." Finally, I said, "But the Switzerland trip is yours if you say yes." "Switzerland , "she said, "is filled with precise, humorless people." "Maybe I should have suggested Paris?" For a minute it seemed as if my change in travel plans would rate a solid "maybe". But she said no again. When we woke up the next morning, she told me that she'd slept on my proposal. "I guess I was a little rude to you last night," she explained. Meanwhile, I'm figuring I'm off the hook for this marriage thing for at least another eight years. I could afford to be generous. "I asked, you said no. It's okay," I said. I might have looked a little too relieved because later that day she gave me a little box. Inside was a gold watch. On the back was inscribed. "Yes. I've reconsidered." I liked the watch, so I did the right thing.

单选题Public speaking fills most people with dread. Humiliation is the greatest fear; serf-exposure and failing to appeal to the audience come a close second. Women hate it most, since girls are pressurized from an early age to be concerned with appearances of all kinds. Most people have plenty of insecurities, and this seems like a situation that will bring them out. If parents, teachers or peers mocked your foibles as a child, you fear a repeat. If you were under pressure to be perfect, you are terrified of failing in the most public of ways. While extroverts will feel less fear before the ordeal, it does not mean they will necessarily do it better. Some very shy people manage to shine. In fact, personality is not the best predictor of who does it well. Regardless of what you are like in real life, the key seems to be to act yourself. Actual acting, as in performing the scripted lines of a character other than yourself, does not do the job. While politicians may limit damage by having carefully rehearsed, written screeds to speak from, there is always a hidden awareness among the audience that the words might not be true. Although, as Earl Spencer proved at his sister Princess Diana's funeral, it is possible both to prepare every word and to act naturally, as script rarely works and it is used as a crutch by most people. But, being yourself doesn't work either. If you spoke as if you were in your own kitchen, it would be too authentic, too unaware of the need to communicate with an audience. I remember going to see British psychiatrist RD Laing speak in public. He behaved like a seriously odd person, talking off the top of his head. Although he was talking about madness and he wrote on mental illness, he seemed to be exhibiting rather than explaining it. The best psychological place from which to speak is an unselfconscious self-consciousness, providing the illusion of being natural. Studies suggest that this state of "flow", as psychologists call it, is very satisfying. Whether in normal life or making speeches, the key is to remind yourself that, contrary to what your teachers or parents may have implied, your best is good enough. In the zone, a strange place of authentic falsehood and shallow depth, play is possible.
